MSI Deployment Problem in GPO Environment

Hello ,
Thanks for reply.

Our upgrade code was changed before few months which we don't know how it was changed.
 
Is there any possibility that this Message "newer version already" comes due to this change ?


As you suggest ,
  Product code always change while version change .
Also DetectNewerInstalledVersion  & RemovePreviousVersions is same as you told .

Plz help .

so it has to be one of the following, but since it works in your local environment there is something else in the client machine which is unknown, need to look deeper.

1. Increment the Version property.
2. Version property of installer project.
3. Change the ProductCode property.
4. Keep the value of "UpgradeCode" property, it needs to stay the same.
5.RemovePreviousVersions to true
6. DetectNewerInstalledVersion to false.

Hello ,

 Scenario is as below
================
 We develop Application & in our 3-4 developer's pc no one face problem such like "newer version already installed"  even if we install any new setup (like 5.51/5.52/..) on any old setup(5.49/5.50)

But at our client 's location (which is in another country) , users are given this setup through GPO in their network .
when end user try to install this MSI , they get message "newer version..." though no new setup installed !!

& we can not replicate / check this issue at our local environment.
& this issue comes since last few setup .

-- Also in every MSI update , we change product version so Product code changes every time .

So plz help in this kind of situation how to replicate/track issue ?

Thanks in Advance
